The air filter is one of the most important parts of a home’s HVAC system. It removes particles and debris from the air before it enters your home, keeping your family safe and healthy.

Custom Filters Direct 20x22x1 air filters are designed to increase your home or office’s indoor air quality by eliminating airborne particles that cause severe allergies and respiratory issues. These air filters fit almost any environment including residential areas, commercial properties, universities, school systems, government institutions, and more.

In order to keep your home allergen-free and comfortable in any season, these AC and furnace air filters come with the specialized electrostatic charge material which helps you to eliminate more than 90% of harmful particulates that floats in your indoor air. Moreover, our air filters also improve the efficiency of your HVAC equipment with their outstanding dust holding capacity.

However, indoor air quality in a home becomes compromised when the filters are dirty. The dirty filters don’t let the clean air pass through and make your HVAC work harder. So, we recommend you check the filters regularly and change them every 60-90 days. If you live in a more polluted area or have pets in your home, change your air filters every month.
